Overview of Perfect Tenses

What is the perfect aspect

The perfect aspect focuses on the completion of an action. You need to use the perfect aspect if the action is / was / will be completed by a specific time. There is usually a very concrete consequence of the action. The action happened in the past, but the result of the action affects the present or the given point in time. This specific point in time is generally determined by a time expression, adverb or a clause (by the time I turn 21). It can also express an action that started in the past, but it is still happening.

Starbucks has served the best coffee for as long as I can remember.

This sentence indicates that Starbucks started serving the best coffee in the past and it still does in the present. Also, note the clause used to express time.

In past and future tenses, the perfect aspect is used to express different timelines of events. Using the perfect aspect, you can indicate that an action happened prior to another action even if both events happened in the past. The same is true for future tenses. Using the perfect aspect, the verb can indicate that an action will happen before another one in the future.

We had been married for 10 years when he finally decided to divorce me. → being married here happened prior to the decision to divorce
She will have finished her studies by 2020. → she will finish her studies first in the future and then 2020 will come

General structure of Perfect Tenses

S + conjugated form of ‘to have’ + Past Participle of the Main Verb + O

The auxiliary verb expressing a previous event is ‘to have’. ‘To have’ is always followed by the past participle of the main verb. Note that many verbs have irregular past participle forms. You can find a list of the most frequently used irregular verbs here. Make sure to conjugate ‘to have’ to agree with the subject of the sentence. The perfect aspect can be used in all tenses: present, past and future. Put the auxiliary verb ‘to have’ in the correct form of the present, past and future tenses to form a whole expression. For example,

I have been to Bali many times.

Note that there are many verbs that have irregular second and third forms. Make sure to learn the most common ones from our list!

How to use perfect tenses

As already mentioned above, perfect tenses are frequently used with different time expression. This time expression can be an adverb or a clause. When you use a clause, it is important to make sure that the tense agrees with the timeline of the events. The event that happened in the more distant past must be in Past Perfect and the event that happened closer to our present needs to be in Simple Past. For example,

We had been friends for years when he finally admitted that he loved me.

The same logic works in future tenses. The event prior to another event needs to be put in a perfect tense. For example,

The plane will have landed by 7 am.

Take a look at the following table to see the correct form of perfect verbs in each tense:

For/since – typical prepositions of Perfect Tenses

Perfect as well as Perfect Progressive Tenses use the prepositions ‘for’ and ‘since’ very often. It is very important to note that a time adverb using for or since in the sentance can change the meaning completely. Let’s take a look at this sentance first:
I have lived in Panama.
Without an adverb it means that I used to live in Panama in the past but I don’t live there anymore. However, look at what happens when we use an adverb:
I have lived in Panama since last summer.
Since last summer refers to the starting point, meaning that I started living in Panama last summer and I still live in Panama.

Let’s look at an example using ‘for’:

My mom has worked as a nurse.
This sentance means that my mom was a nurse once but today she might have another job.
My mom has worked as a nurse for 2 years.
This means that my mom started working as a nurse 2 years ago and she still works as a nurse today.

Overview of Progressive Tenses

What is the progressive aspect

The progressive aspect allows the speaker to express an action that is unfinished or in progress. They generally refer to an action in a given moment, not regularity. The aim of the speaker is to refer to an action that is ongoing at a given moment. It can also be used to describe an action withing a given time frame.

For example:
She is playing with her phone during the break.
The professor was explaining the solution when the bell rang.
I was walking home when it started raining.

How to use the progressive aspect

If you have decided to use progressive aspect, the next step is to decide which tense to put the verb into. The progressive aspect can be used in all three tenses: present, past and future. In each tense, you must use the auxiliary verb of Progressive Tenses in the correct tense.

General structure of Progressive Tenses

S + conjugated form of ‘to be’ + Progressive Participle of Main Verb + O

Progressive Tenses use ‘to be’ as an auxiliary verb that must be followed by the progressive participle of the main verb. Remember that ‘to be’ needs to agree with the subject at all times. Note that ‘to be’ is always followed by the -progressive participle of the main verb in progressive tenses to express continuity. You may see ‘to be’ followed by the past participle of the verb which is used in Passive Voice that is not a tense.

Take a look at the highlighted area to see the correct form of progressive verbs in each tense:

Verbs that are usually not used in Progressive Tenses
(Non-continuous Verbs)

Some verbs that express states and not actions or processes cannot be used in Progressive Tenses. The easiest way to decide if you can use a verb in progressive form is to ask yourself if you can see somebody doing it. If you cannot see someone doing it, stick to Simple Tenses. The verbs usually express something abstract such as emotions, opinion or possession.

  • Senses / Perception: to feel, to hear, to see, to smell, to taste
  • Opinions / beliefs: to assume, to believe, to consider, to doubt, to feel (=to think), to find (=to consider), to suppose, to think*
    *‘To think’ cannot be used in a progressive tense if it expresses opinion. However, if it expresses the action of someone thinking about something without any result, it can be used in Progressive Tenses.
  • Mental states: to forget, to imagine, to know, to mean, to notice, to recognize, to remember, to understand
  • Emotions: to envy, to fear, to dislike, to hate, to hope, to like, to love, to mind, to prefer, to regret, to want, to wish
  • Measurement: to contain, to cost, to hold, to measure, to weigh
  • Others: to look (=to resemble), to seem, to be (in most cases), to have (=to own)

Exceptions
Some verbs have a different meaning in Progressive and Simple Tenses. Make sure to note these when forming sentences or translating them.

  • This massage feels nice. → perception of the massage’s quality
  • Franz is feeling sick from the salad. → his health is currently affected by the salad
  • My neighbor has 20 cats. → expressing ownership
  • I’m having a great time with you. → being entertained, feeling good
  • You can’t see the London Eye from here. → perception
  • I’m seeing my mom later during the week. → planning on meeting

Overview of Simple Tenses

What is the Simple Aspect?

Simple tenses are used to express actions that are repeated, factual, normal, or always true.

In simple present tense, it often refers to a habitual, regular action or anything that is in occurrence but is not necessarily happening right now. These are usually timeless statements. It is used to express facts. The focus is on the occurrence, not the process or if the action is complete. For example,

Starbucks serves the best coffee in town.

This sentence clearly indicates that you can find the best coffee at Starbucks, but they might not be serving it right now. (They may be closed.)

Other examples:

She teaches English to elementary school kids.
The paper arrives at 7 am every day.
You need two tablespoon of sugar for this recipe.

Verbs Usually Used in Simple Tenses (Non-continuous Verbs)

Some verbs that express states and not actions or processes are generally used in Simple Tenses. These can be called stative verbs or non-continuous verbs. The easiest way to identify such verbs is to examine if you can see someone performing the action. If you cannot see someone doing it, you should usually use Simple Tenses. The verbs usually express something abstract such as emotions, opinion or possession.

Senses / Perception: to feel, to hear, to see, to smell, to taste

Opinions / beliefs: to assume, to believe, to consider, to doubt, to feel (=to think), to find (=to consider), to suppose, to think*
* ‘To think’ cannot be used in a progressive tense if it expresses opinion. However, if it expresses the action of someone thinking about something without any result, it can be used in Progressive Tenses.

Mental states: to forget, to imagine, to know, to mean, to notice, to recognize, to remember, to understand

Emotions: to envy, to fear, to dislike, to hate, to hope, to like, to love, to mind, to prefer, to regret, to want, to wish

Measurement: to contain, to cost, to hold, to measure, to weigh

How to Use the Simple Aspect

Once you have decided to use the simple aspect, verb formation is very easy. The simple aspect can be used in all three tenses: Simple Present, Simple Past and Simple Future. There is no auxiliary verb needed for affirmative sentences in simple present and simple past; we simply use the first form of the verb in the correct tense.

General Structure of Simple Tenses

Overview of English Verb Tenses

Introduction

Learning verb tenses is always the tricky part of learning a language. Especially, when a language has 12 of them. It might sound scary at first but once you understand the logic behind why there are so many in the English language, you’ll be able to use them with confidence. In this post, I’ll give you a general overview on tenses that you can use as guidence before you dive into each tense one by one. Take a look at the following chart with all the tenses:

Verb Tenses Chart
12 English Verb Tenses

*S refers to subject as the performer of the action
E.g. If we examine the following sentence: ‘Mary makes a coffee.’ → Mary is the subject.
*O refers to the object on which the action is performed
E.g. In the above-mentioned sentence the coffee is the object.

Verb Tenses

In the English language, tenses are categorized according to two characteristics: tense and aspect as you can see it in the table above. Understanding tenses is more intuitive as there are past, present and future tenses, depending where the action takes place in time compared to our present.

Verb Aspect

The aspect is a bit more complicated. We differentiate three aspects: simple, progressive and perfect. Each tense has a simple, a progressive, a perfect progressive and a perfect version, adding up to 12 tenses. However, it is enough to understand the logic behind the aspects and you will know when to use them. Each aspect follows the same structure in all tenses, therefore, you will only need to learn the logic behind the structure of each aspect and you will be able to put it in past, present of future forms.

Don’t confuse tenses with clauses

In the table above, you can find all tenses in each aspect. Note that each of these tenses can be used in different clauses such as conditional and passive voice so do not confuse the two. I encourage you to check out the overview pages of each aspect before jumping into the tenses so that you will have a general understanding of the structure. Always use a verb tenses chart for guidance.

Useful abbreviations in verb structures

Most verb tenses in the English language consist of an auxuliary verb (helping verb) and a main verb, meaning that there are auxiliary verbs assisting the action verb to express the right time and aspect. At the beginning of each page, you will find a clear guideline how to form the structure in that specific tense. I will be using the following abbreviations for different verb forms:

  • Bare infinitive: Bare infinitive is the infinitive form of the  You form the first form of the verb by dropping the ‘to’ from the infinitive form.
    For example: to make → make
    to play → play
  • Simple Past: The second form of the verb is the past form or -ed form. Note that there are many irregular verbs in the English language. You can find an extensive list here.
  • Past Participle: The third form of the verb is the Past Participle. It is formed by adding -ed to the end of the verb. However, the irregular verbs have irregular Past Participle forms, as well, that you can learn along with the second forms. The third form usually follows the auxiliary verb ‘to have’ in Perfect Tenses.
  • Progressive Participle: The -ing form of the verb is created by adding -ing to the end of the verb. There are some irregularities in spelling that you can find here. The -ing form is generally used in Progressive Tenses and it is follows the auxiliary verb ‘to be’.

Always keep in mind

There are some general rules in English structures that can help you get the right form:

  • ‘Have’ as an auxiliary verb is always followed by the perfect participle of the verb.
    For example: I have been dreaming about a chocolate cake for so long.
  • ‘To be’ in progressive tenses is always followed by the progressive participe of the verb. If it is followed by the perfect participle, it refers to Passive Voice which is not a verb tense.
    For example: Bob was lying to me the whole time. → progressive
    I was being lied to the whole time. → Passive Voice
  • When you got the correct structure of the chosen aspect right, it is always the first auxiliary verb that needs to be put in the chosen tense.
    For example: ‘to be going to the movies’ →  She was going to the movies.
  • The first auxiliary verb of the tense must always agree with the subject. The form of all other auxiliary or action verbs will be determined by the auxiliary verb standing in front of them.
    For example: She has been knitting this sweater for months. → Here, the form of ‘to have’ must agree with she or third person singular.
